Xiaolin Sun ‘20 and Prof. Gember-Jacobson attended ACM SIGCOMM 2019, “the flagship annual conference of the ACM Special Interest Group on Data Communication (SIGCOMM) on the applications, technologies, architectures, and protocols for computer communication.” Prof. Gember-Jacobson presented a keynote “Localizing Routing Configuration Errors Using Minimal Correction Sets” at the co-located ACM SIGCOMM 2019 Workshop on Networking and Programming Languages. The keynote focused on Prof. Gember-Jacobson’s ongoing research to automatically diagnosis human- and software-induced network configuration errors that cause networks to improperly forward traffic. Xiaolin has made significant contributions to the research and was awarded a Student Travel Grant to attend the conference.
